Tov all whom it may concern:

Be it known that I, WILLIAM S. OVERLIN, a citizen of the United States,residing at Fulton, in the county of Multnomah and State of Oregon, haveinvented a new and useful Sawin -Machine, of which the following is aspec cation.

My invention relates to sawing machines in which the saw is attached toa reciprocating sliding head. I The sliding head is caused toreciprocate, between 'de's, back and forth by a connecting ro the-connecting rod being so attached to the sliding head that the saw doesnot move across the log in a horizontal plane, but oscillates, thusclearing the cut from sawdust which greatly facilitates the operation ofthe saw.. The saw will also feed into the cut made as fast as desired.It is also arranged so that if the tumedinto the desired log to be sawedshould not touch the ground at the place to be sawed, the entire machinemay be fastened to the log without further support. I attain theseobjects by the mechanisms illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation of the entire machine, showing it inposition on the log. Fig. 2 isa to elevation of the mechanism. Fig. 3 isan e arged view of the sliding head illustrating the take-up for theshoes and the connecting arm that causes the saw to oscillate. Fig. 4 isthe top elevation of the same.

Similar numerals refer to similar parts throughout the several views. I

1 is the base which is fastened to the frame and upon which the powergenerator is placed. 4

2 is that part of the frame to which the base 1 is attached. .3 is aremaining part of the frame. Connecting frame 2 with frame 3 is a swivel'oin. 4 which is rigidly fastened to 2. 3 slides within 4. When positionit may be held there by setscrew 5 which extends through tee8 to theouter end of which the guides 10 and 11 are fastened; this secures theframe of the machine to the guides for the sliding head. To the end ofcasting 9, which passes through tee 8, gear 12 is keyed.

15 is thebelt which delivers power from the generator to the pulley 14.Attached to 14 is a spur pinion 13 which meshes with 12. As 12 revolvesthe shaft to which it is keyed, or otherwise fastened, also revolves;this in turn causes crank 16 to rotate. Pitman 17 being secured to 16and 18 causes the sliding head, to which the saw is attached, tooscillate two strokes. Connecting rod 17 is attached to 18 which isfastened to each side of, the sliding-head 22 and 23. Ann 20 is alsofastened to 17 at '19.. The saw end of 20 is.

the driving end of 17 moves in circle, and

since it is held in place at 18, it may be seen that a-point 19 on arm20 is caused to move up and down on an are about 26 as a center,

but since the saw is fastened to the other end of 20, a sim lar motionis transmitted to it. This is necessary for if the saw is drawn back andforth across the log in a horizontal plane the sawdust will be left inthe lo Secured to cross bars 26 are adjustable s oes 24; as they wearthey may be taken up by means of a slot 25. To hold the sawin alinementand to prevent wabbling, or buckling, a. guide 27 is used. a

28 is a saw and 30 are set screws to secure the-saw to the drivingmechanism.

I am aware that prior to my invention sawing machines have been made,but I do claim the machine, as herewith illustrated, does contain newand useful mechanisms and I therefore claim;

1. A sawing machine comprising a frame,

' driving mechanism mounted thereon, a

guide, a driving head slidably mounted in the uide, a saw pivotallyconnected with said ead, a pitman pivoted to the head and having pivotalconnection with the saw, and means connecting the pitman and drivingmechanism.

2. A sawin machine comprising a'frame, driving mec anism thereonincluding a guide, a driving headslideble in the guide, saw arin foroscillating the saw as it is recipa saw, an arm connected rigidly at oneend roceted by the head.

with the saw and pivotally connected between its ends to the drivinghead, and a pit- WILLIAM OVERLIN 5 man connected with the head forreciprocat- Witnesses:
